Mental retardation is a condition characterized by impaired or below average cognitive functioning, concurrent deficits in adaptive abilities and manifested before the age of 18 (American Psychiatric Association, 1994). The diagnosis is usually based on the results of an individually administered test of cognitive abilities (IQ test) and an assessment of adaptive behavior. Within the condition of mental retardation, four levels of severity have been described (APA, 1994). Each of these categories is noted below.
